Advanced G65 Macro: Precise Radius Increment for CNC Milling

CNC Program

;A = #1 (Start Angle 0 degrees)
;B = #2 (Start Radius)
;C = #3 (Increment angle for accuracy calculations.)
;I = #4 (Finish Angle)
;J = #5 (Finish radius)
;K = #6 (Milling feed)

#7 = #4 / #3 ;1) Total no. of moves 70 / 0.01
#8 = [[#5 - #2] / #7] ;2) Increase in radius 37-35/7000
N1 #2 = #2 + #8 ;3) Next Radius i.e. 35+inc. radius.
#1 = #1 + #3 ;4) Increase in angle
#9 = #2 * COS [ #1 ] ;5) New X axis position
#10 = #2 * SIN [ #1 ] ;6) New Y axis position
